Hmm, but doesn't that disagree with my intuition? Unless I misunderstood you? I'm saying green looks similar to nearby colours so should take up less space on a perceptual colour wheel (e.g. blue and green look much more similar than blue and red to me, so blue and green should be much closer to each other). But you're saying we can perceive many shades of green, presumably with the implication that it should take up more space on perceptual colour wheel. That xckd article seems to agree with me: a huge chunk of the physical colour space is simply lumped into "green", rather than given lots of different names at you'd expect if different bits appeared visually distinctive. In fact, this all is not necessarily a contradiction: perhaps we can distinguish between extremely similar shades of green, better than other colours, but experience even very different shades of green as feeling subjectively similar.
